Calendar and Contacts not syncing after iOS 9 upgrade

My iCloud and Exchange calendars and contacts stopped syncing after upgrading to iOS 9 on an iPhone 6. Mail is fine and iCloud notes are syncing correctly. It seems to be specifically calendar and contacts. I tried deleting the Exchange account and re-adding it with no luck. From desktop to web is working for both iCloud and Exchange, so definitely, the phone has the issues.


Anyone have a solve or things to check?

iPhone 6, iOS 9

I don't know whether my contacts were affected, but I was experiencing the calendar issue in a big way, with my phone and ipad. Deleting and re-setting-up the account fixed my calendar issue.


I have noticed over time -- since long before the upgrade to iOS 9 -- that contacts spuriously disappear from my 'contacts' list. Most problematic. And as far as I know there is no reliable fix for that.

Just tried it. It resolved nothing. I probably lost a bunch more contacts, though, and maybe some appointments. Time will tell.


Apple isn't very good at synchronization logic.


Something else I observed, is that in my VIP folder, I can click 'Edit' to reveal message tick-circles, and controls for the mailbox -- but absolutely everything there is greyed out so I can do nothing. I discovered this when I decided to try 'mark all as read'.

THIS WORKED FOR ME:


Settings

iCloud

scroll to bottom and Sign Out. (SIGN COMPLETELY OUT, NOT JUST CONTACTS.)

Do not keep items on iPhone. (this can take a minute or so, so don't panic.. you're phone is not freezing)


RE-Sign In to iCloud. Everything was there, and synced back and forth to Mac & iPhone.


Hope this helps!!

Hello, I am having the same issue. If I add a contact or an appointment in the phone, it will sync to all devices. If I delete or edit a contact or appointment in say the ipad, it will sync to all devices except the phone (iphone 6).


I have been on support chat and also had a phone call from one of the support team last night and for some reason syncing started working while I was speaking with him.


This morning it is back to not working properly. I say properly as it will work sometimes, after a long delay, or sometimes I have to switch the phone totally off and reboot.


It is basically very buggy and this has only been since the ios 9 update. I have mentioned to support that I am not alone with this issue, as at first they were suggesting it was a phone fault. it is a new phone though and the issue only started after installing ios 9.


I have another call tomorrow night. If they find a fix, I will update!
